Q: Passage: Both Sui and Tang empires occupied the same location. In 582, Emperor Wen of the Sui dynasty sited a new region southeast of the much ruined Han Dynasty Chang'an to build his new capital, which he called Daxing (大興, “Great Prosperity”). Daxing was renamed Chang'an in year 618 when the Duke of Tang, Li Yuan, proclaimed himself the Emperor Gaozu of Tang. Chang'an during the Tang dynasty (618–907) was, along with Constantinople (Istanbul) and Baghdad, one of the largest cities in the world. It was a cosmopolitan urban center with considerable foreign populations from other parts of Asia and beyond. This new Chang'an was laid out on a north-south axis in a grid pattern, dividing the enclosure into 108 wards and featuring two large marketplaces, in the east and west respectively. Everyday, administrators of the two marketplaces would beat gong for three hundred times in the morning and evening to signify the start and stop of business. People lived in the wards were not allowed to go outside after curfew. Officials with higher-ranking had the privilege to live closer to the central avenue. Chang'an's layout influenced city planning of several other Asian capitals for many years to come. Chang'an's walled and gated wards were much larger than conventional city blocks seen in modern cities, as the smallest ward had a surface area of 68 acres and the largest ward had a surface area of . The height of the walls enclosing each ward were on average 9 to in height. The Japanese built their ancient capitals, Heijō-kyō (today's Nara) and later Heian-kyō or Kyoto, modelled after Chang'an in a more modest scale yet was never fortified. The modern Kyoto still retains some characteristics of Sui-Tang Chang'an. Similarly, the Korean Silla dynasty modeled their capital of Gyeongju after the Chinese capital. Sanggyeong, one of the five capitals of the state of Balhae, was also laid out like Chang'an.

Q: Passage: By August 1940 the Battle of Britain was intensifying. Most of the battles thus far were in daylight, leaving night-fighter crews frustrated. Now based at RAF Digby in Lincolnshire and operating from the satellite airfield at Wellingore the unit formed part of No. 12 Group RAF defending British air space north of London. On the night of 24 August 1940 Braham took off and patrolled the Humberside area. The Blenheim was piloted by Braham, and contained air gunner Sergeant Wilsdon and aircraftman and trained radar operator N. Jacobson. Braham was directed to an aircraft held in searchlights but he closed too fast and overshot. His gunner succeeded in damaging the aircraft sufficiently and a searchlight crew saw it crash into the sea. It was identified as a Heinkel He 111. Braham's only other interaction with the enemy occurred at Ternhill, when a Junkers Ju 88 dropped bombs on the airfield destroying 13 Avro Ansons and damaged 20 more. Braham survived the attack uninjured.

Q: Passage: Pallikaranai wetland is a freshwater marsh in the city of Chennai, India. It is situated adjacent to the Bay of Bengal, about south of the city centre, and has a geographical area of . Pallikaranai marshland is the only surviving wetland ecosystem of the city and is among the few and last remaining natural wetlands of South India. It is one of the 94 identified wetlands under National Wetland Conservation and Management Programme (NWCMP) operationalised by the Government of India in 1985–86 and one of the three in the state of Tamil Nadu, the other two being Point Calimere and Kazhuveli. It is also one of the prioritised wetlands of Tamil Nadu. The topography of the swamp is such that it always retains some storage, thus forming an aquatic ecosystem. A project on 'Inland Wetlands of India' commissioned by the Ministry of Environment and Forests, Government of India had prioritised Pallikaranai marsh as one of the most significant wetlands of the country. The marsh contains several rare or endangered and threatened species and acts as a forage and breeding ground for thousands of migratory birds from various places within and outside the country. The number of bird species sighted in the wetland is significantly higher than the number at Vedanthangal Bird Sanctuary.
